Father and son are accused of overcharging and defrauding dozens of road accident victims.

Attorney Ulrich Roux said Ronald and Darren Bobroff aren't aware of any charges that have been brought against them.

"They will obviously have be informed as to what the charges relate and exactly what it entails and once they're informed then they will be in position to properly assist the National Prosecuting Authority or the South African Police Service."

Roux did not say why his clients have gone to Australia.

He said they left the country freely without breaking any laws or contravened any restrictions imposed on their movement.
